Screen-printed solar cells were first developed in the 1970's. As such, they are the best established, most mature solar cell fabrication technology, and screen-printed solar cells currently dominate the market for terrestrial photovoltaic modules. The key advantage of screen-printing is the relative simplicity of the process.
A successful application of this printing method for the metallization of heterojunction solar cells has been demonstrated. 369 First attempts to use rotary screen printing for the metallization of silicon solar cells date back to the late 1990s 362 but have not been pursued further.
Sebastian Tepner and Andreas Lorenz contributed equally to this work. This paper presents a comprehensive overview on printing technologies for metallization of solar cells. Throughout the last 30 years, flatbed screen printing has established itself as the predominant metallization process for the mass production of silicon solar cells.
The key advantage of screen-printing is the relative simplicity of the process. There are a variety of processes for manufacturing screen-printed solar cells. The production technique given in the animation below is one of the simplest techniques and has since been improved upon by many manufacturers and research laboratories.
The paste can be pushed through the openings in the screen using a squeegee to form a pattern of paste on the cell surface under the screen. Screen printing is used to form the rear aluminium electrode and the front surface silver grid (busbars and fingers) on the silicon nitride antireflection coating (ARC).
When the cell is cofired (in the next production step), the paste etches through the silicon nitride and silver contacts the underlying silicon to form the n -type contacts to the solar cell. This tutorial focuses on the silver screen printing process as the design of the screens is critical for the way the pattern is used to form the metal grid.
